Had to wait for raid5 resync to finish.
Was then able to do fsck without errors (before was running out of handles
in qlogicfc when both were simultaneous)
Now running the disks on ext2 with 2.2.6-pre6 and performance is better
except for sequential read and random write.
(saga of story is that ext3 and tiobench didn't get along very well with 4G
test files).
This is 7x36G fibre channel
